1. hclwrite: Various new "TokensFor..." functions …

   The "TokensFor..." family of functions all aim to construct valid
   raw token sequences representing particular syntax constructs.
   
   Previously we had only "leaf" functions TokensForValue and
   TokensForTraversal, but nothing to help with constructing compound
   structures.
   
   Here we add TokensForTuple, TokensForObject, and
   TokensForFunctionCall which together cover all of the constructs
   that HCL allows static analysis of, and thus constructs where it's
   likely that someone would want to generate an expression that
   is interpreted purely by its syntax and not resolved into a value.
   
   What all of these have in common is that they take other Tokens
   values as arguments and include them verbatim as part of their
   result, with the caller being responsible for making sure these
   smaller units are themselves valid expression tokens.
   
   This also adds TokensForIdentifier as a convenient shorthand for
   generating single-identifier tokens, which is particularly useful
   for populating the attribute names in TokensForObject.
